Information on the histopathological profile of children with glomerular diseases from developing countries is limited and variable. We retrospectively reviewed the clinical records of 275 children who underwent kidney biopsy for suspected glomerulonephritis (GN) at the Department of Pediatric Nephrology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh, over a 5-year period, between July 2012 and June 2017. All kidney biopsies were percutaneous, performed using standard practices worldwide, and evaluated by light and immunofluorescence microscopy. Patients with congenital nephrotic syndrome, inadequate biopsy (n = 22), and incomplete clinical records (n = 58) were excluded from the study, and 195 patients with a median (range) age of 144 (8–204) months, of whom 60% were boys, were included in the study. The chief indications for biopsy included nephrotic syndrome, with steroid resistance (31.3%); presentation at <1 year or above 10 years of age (22%); atypical presentation with gross hematuria, impaired renal function, hypocomplementemia, or persistent hypertension (6.7%); suspected secondary cause (12.3%); or, in steroid-dependent patients, before therapy with calcineurin inhibitors (12.8%). Other indications included rapidly progressive GN, delayed resolution of postinfectious GN, and to determine the etiology of unknown glomerular chronic kidney disease.
The most common histopathological diagnosis was mesangial proliferative GN (32.8%), followed by membranoproliferative GN (20.5%), minimal change disease (13.3%), lupus nephritis (9.2%), focal segmental glomerulosclerosis (6.2%), crescentic GN (6.2%), immunoglobulin (Ig) IgA nephropathy (4.6%), Henoch–Schonlein purpura nephritis (4.1%), and diffuse proliferative GN (3.1%). Among 18 patients with lupus nephritis, 13 showed Class IV nephritis, 4 biopsies showed Class II, and one had Class V lupus nephritis.
The finding of mesangioproliferative GN as the most common histopathological type of GN, is similar to those of previous studies from Bangladesh, including our center, and from other countries., The lack of predominance of minimal change or focal segmental glomerulosclerosis as the predominant histopathology, and the low rate of reporting of IgA nephropathy in our study, as compared to findings from other countries,,, might reflect differences in practice indications for biopsy, referral bias, or geographical variations in the prevalence of glomerular diseases. The findings of Class IV nephritis as the most common histopathological subtype are consistent with what is understood of childhood-onset systemic lupus erythematosus.
Renal biopsy reliably enables the diagnosis and assessment of the prognosis of pediatric glomerular diseases. An understanding of the relative prevalence of various histopathological subtypes is useful in predicting the underlying histology and guiding the management of children with glomerular diseases.
